I have just been watching the film Creation on BBC iPlayer, and found the portrayal of Emma Darwin a bit too orthodox, considering that she was a Unitarian (though of course Unitarianism was different then to what it's like now), so I decided to Google for background information. Although the family attended the local Anglican church, Emma made them turn around when the Nicene Creed was recited, because it is Trinitarian. She also enjoyed discussing evolution with her husband, although she believed in creation.
It seems really bizarre now that millions of ordinary people actually literally believed in God creating the Earth in 7 days and all that.
The film also seems to me to have made Darwin's inner struggles a bit too anguished and laudanum-fuelled. It's true that he feared the impact that publication of the theory of evolution would have on the world, but it did not abolish trust, hope, love and altruism, as he is portrayed in the film as fearing.
And why wasn't the film called Evolution? (I suppose because less Americans would have gone to see it...)
